My guys have eaten paper towel but I buy the bargain brand. Is your mini lop sensitive in the tummy? Our nethie Ben went into a gas episode the other day after getting too many treats by accident. We isolated him (he could still see his lady) with a new litterbox full of hay, some favorite veggies, even a few pellets, and a big bowl of water and one of water + grenadine. We did the 1cc of simethicone thing every hour, with as much water as he'd let us syringe feed him each time, plus had a rice sock for him. It took a few hours, but he eventually started eating and pooping.
For your guy I too would push the fluids like angieluv said. Pedialyte is the best option, and keep up the simethicone. You may also consider a bit of pain medicine if you have it and he has some food and water in his stomach. Pain meds shouldn't be given to a dehydrated bunny or one with an empty stomach. Meloxicam (Metacam) lasts for 6 mo after compounding, and baby aspirin and ibuprofen are also options. Some gentle belly massages--especially feel around to see if you can feel hard, bloated areas--can help. Pumpkin puree is also a lifesaver, I'd get some of that too.
